GEA Refrigeration Technologies, part of the internationally active GEA Group, is a synonym

for industrial refrigeration technology. Since the end of the 19th century, it has been our busi-

ness to cool processes and products, and to control the temperature of goods in transport.

You will find our solutions in the food and beverage sector; in the petrochemical, chemical,

and pharmaceutical industries; on fishing ships; in natural gas liquefaction; in infrastructure

facilities; and in ice factories. We are also at the top with know-how when it comes to refrige-

ration at leisure facilities. After all, we have been excited about refrigeration for decades now.

As a result, our staff enthusiastically goes about its development and production projects – to

include preventive and remedial maintenance of your refrigeration systems.

This enthusiasm is highly apparent in the daily work of all companies in our Segment.

Whether it’s complete systems or individual valves: we have the experience in every section

of our company to optimally design, manufacture, and install refrigeration systems. And to

take full advantage of this experience, we not only carry out development in our own compa-

ny: we also manufacture, assemble, and test the core components. A chain is, after all, only

as strong as its weakest link: and this also applies equally well to refrigeration technology,

cooling processes, and cooling chains.

This makes it all the more important that you have a partner – in GEA Refrigeration Techno-

logies – that has learned to master refrigeration from A to Z. And all of this since 1896, when

Willem Grasso founded his refrigeration division. From this history of GEA Refrigeration

Technologies, you will profit in the form of technical expertise and top sector know-how.

But we all live in the present and think about the future. We ponder a future in which more

and more processes need energy around the world, and fewer natural resources are avai-

lable. As a result, we have taken it as our goal to create solutions that are not only long-life

and cost-effective, but also energy-saving and environment-protecting. We feel obligated to

sustainability in many respects. Our objective is to produce longlife and material-saving pro-

ducts over the long run – as well as products that use environmentally benign refrigerants.

And we aim to produce efficiently. But our responsibility does not end at the factory gate.

As a result, we take great pains to ensure that our systems are energy-efficient and that they

protect the climate. With GEA Refrigeration Technologies, you can also count on optimal

economy: saving energy indeed means reducing money spent for energy. At the same time,

you protect the environment. Thanks to our refrigeration technology, your processes will run

more economically and more ecologically. To maintain our standard of living and to assure

quality of life for future generations as well.

Our claim of combining economy with saving natural resources is reflected in all compon-

ents of our company, such as the following: compressors, chillers, heat pumps, ice machines,

fittings and valves, control systems, and many, many more. You can find proof of the above

throughout the world. Our international corporate network – and above all our reference

projects – are spread all over the globe.

Service - Made by GEA Bock I 4


Over 75 years ago, when the refrigeration and air-conditioning

industry was still in its infancy, our company's founder, Wilhelm

Bock, had a vision: he wanted to build first-class and reliable refri-

geration machines. In the following decades Bock developed into

one of the world's leading manufacturers of refrigeration and air-

conditioning compressors.

Today, GEA Bock offers as part of GEA Refrigeration Technologies

the right compressor for all fields of commercial-, industrial-, rail-,

bus- and transport refrigeration.

Sustainable refrigeration technology is in the focus of product

development at GEA Bock for many years. Already in the mid-90s

Bock compressors were the heart of the first transcritical CO2 refri-

geration systems in mobile and stationary applications.

Today GEA Bock offers a wide range of CO2 compressors for

subcritical and transcritical application areas.

Be inspired. By our new products, our established product series

and the entire passion that goes into each of our products.

The refrigerant R744Based on our current semi-hermetic product range, with its outstanding advantages and

features, as well as our longstanding activities, we are now expanding the bottom end of

our CO2 compressor series for subcritical cascade systems.

Especially suited to supermarket refrigeration applications and industrial refrigeration.

Max. permissible operating pressure up to 55 bar at the high pressure side and 40 bar at

the low pressure side.

Special features

As Bock compressors are of extremely high quality and robust, the coordination with

CO2 is limited primarily to the motor design together with the individual mechanism

adjustments as well as small modifications in the valve and seal areas.

This permits the greatest possible level of operational safety through the extensive use

of tried-and-trusted standard parts. In addition, there are the best possible conditions for

economic spare part storage.

The refrigerant CO2

Within refrigeration technology, carbon dioxide (CO2) is known by the name R744 and

has a long history.

It is a colourless gas which liquefies under pressure and has a slightly acidic smell and

taste. Carbon dioxide has no ozone depletion potential (ODP = 0) and a negligible direct

effect on global warming (GWP = 1) when used as a refrigerant in closed systems.

It is not combustible, is chemically inactive and heavier than air. Carbon dioxide has a

narcotic and asphyxiating effect on humans only at higher concentrations.

Carbon dioxide is available naturally in large quantities.

Oil

The compressors are equipped with Bock C85E, a special oil filling,

which is available directly from GEA Bock. This is a synthetic ester

oil with high thermal load resistance, allowing good mixing solubility

with CO2. It possesses a special additive, which protects the compres-

sors against wear, even when subjected to extreme loads, such as tho-

se which exist in CO2 systems. This oil can be used both in transcritical

and subcritical systems.

CO2 Notes

Operating limits

Compressor operation is possible within the limits shown on the

application diagrams. Please note the coloured areas. Compressor

application limits should not be chosen for design purposes or con-

tinuous operation.

Restrictions to the operating limits may occur when using the Bock

EFC (Electronic Frequency Control). Further information see separate

brochure "Bock semi-hermetic compressors - Electronic Controls".

Performance data

The performance data for CO2 are based on 20 K suction gas super-

heat without liquid subcooling, at 50 Hz power supply frequency.

These are preliminary values as no uniform reference data are avai-

lable. Besides which the influence of the oil part on refrigeration per-

formance is largely unknown. Variations cannot be excluded.

Conversion factor for 60 Hz = 1,2

Performance data for other operating points, see GEA Bock

Technical data° CO2 Compressors (subcritical)

Explanations:

Tolerance (± 10%) relates to the mean value of the voltage

range. Other voltages and current types on request.

- The specifications for max. power consumption apply for

50 Hz operation. For 60 Hz operation, the specifications

have to be multiplied by the factor 1.2.

The max. working current remains unchanged.

- Take account of the max. operating current / max. power

consumption when designing contactors, leads and fuses.

Since the beginning of the 1990‘s, GEA Bock, together with leading

institutes and manufacturers, has concerned itself with the

development of compressors for the transcritical CO2 process.

In the past years, CO2 compressors by GEA Bock could be

established in many areas of application.

At a glance° CO2 Compressors (transcritical)

Important information

Transcritical CO - 2 applications are still in the development phase

They require a completely new kind of system and control -

They are not a general solution for the substitution of F-gases -

We specifically point out that all information in this brochure has been made based on our current level of knowledge and may change at any -

time due to further development. Legal claims regarding the accuracy of the information cannot be made at any time and are hereby excluded.

Compressors can only be made available for selected projects -

Operation and warranties are subject to a separate agreement -

The current program of transcritical CO2 compressors was now

extended by the 4-cylinder model HGX34 CO2 T with displace-

ment of 9,9 to 20,1 m3/h.

Within refrigeration technology, carbon dioxide (CO2) is known by

the name R744 and has a long history. It is a colourless gas which

liquefies under pressure and has a slightly acidic smell and taste.

Carbon dioxide has no ozone depletion potential (ODP=0) and a ne-

gligible direct effect on global warming (GWP = 1) when used as a

refrigerant in closed systems.

CO2 as a refrigerant

It is not combustible, is chemically inactive and heavier than air.

Carbon dioxide has a narcotic and asphyxiating effect on humans

only at higher concentrations.

As carbon dioxide is less energy efficient than other refrigerants,

recently work has particularly concentrated on optimising plant

technology for specific applications. Carbon dioxide is available na-

turally in large quantities.

Special features CO2 transcritical

Based on the high CO2 pressure and the low temperature of the

critical point of 31°C (74 bar), transcritical operating conditions oc-

cur at higher temperatures at the heat exchanger. In this case, in

comparison to subcritical applications, the refrigerant CO2 can no

longer be condensed. In this case, the refrigerant gas is heated in

a gas cooler. The temperature and the pressure are dependent on

each other, compared to the subcritical operation.

A special feature in these operating points is the necessary regula-

tion of the high pressure at the so-called optimal high pressure. In

doing this, the greatest possible enthalpy difference at the evapora-

tor and the lowest possible power consumption of the compressor

should be reached. In this way, the maximum coefficient of perfor-

mance (COP) of the system is achieved. An additional valve with

intelligent control after the high-pressure heat exchanger is needed

for this in the system.

For additional technical data see GEA Bock software.

Performance data

The performance data for CO2 are based on 10 K suctiongas super-

heating at 50 Hz mains frequency.

In case of subcritical operating conditions, no liquid undercoo-

ling takes place. The performance data for transcritical operating

conditions are specified close to the "optimal high pressure".

The optimal high pressure is thereby related to an ideal cyclic

process.

which is available directly from GEA Bock. This is a synthetic ester

oil with high thermal load resistance, allowing good mixing solubility

with CO2. It possesses a special additive, which protects the compres-

sors against wear, even when subjected to extreme loads, such as tho-

se which exist in CO2 systems. This oil can be used both in transcritical

and subcritical systems.

At a glance

GEA Bock has developed this new radial piston compressor with

Obrist Engineering GmbH, who has also worked on the develop-

ment of CO2 compressors for a long time.

Because of the radial cylinder arrangement on one level and the

combination with CO2 as a working substance, extremely small di-

mensions can be realized. It is a compressor with future potential

- ideal for small to medium capacities.

The compact engineering design, universal possibilities for instal-

lation (vertically or horizontally) as well as the 6-cylinder construc-

tion that is radially arranged on one level, result in completely new

dimensions for the working range and potential for development

of the compressor itself (potential operating pressure up to 130

bar).

Important information

Transcritical CO - 2 applications are still in the development phase

They require a completely new kind of system and control -

They are not a general solution for the substitution of F-gases -

We specifically point out that all information in this chapter has -

been made based on our current level of knowledge and may

change at any time due to further development. Legal claims regar-

ding the accuracy of the information cannot be made at any time

and are hereby excluded.

Special features

Simple total construction, aligned to the special requirements in -

the transcritical sector

Only two surface seals on the entire compressor (housing cover, -

electrical terminal board)

Pot-shaped, closed housing made of spheroidal cast iron for -

maximum pressure strength

Complete power train integrated in the housing, no cylinder -

cover required

Only a few small high-pressure compartments -

Valve operation according to the uniflow principle, the suction -

gas is pushed in one direction through the piston and is thus

compressed. There are no alternating gas movements and a

minimum amount of gas pulsation

Centrifugal lubrication with integrated oil separation -

Excellent operating characteristics – radial arrangement of six -

cylinders on one level

Well dimensioned drive motors, partially suction gas cooled, in -

2 and 4 pole versions (2.900 and 1.450 rpm)

Notes

Refrigeration-machine oil


which is available directly from GEA Bock. This is a synthetic ester oil

with high thermal load resistance, allowing good mixing solubility

with CO2. It possesses a special additive, which protects the com-

pressors against wear, even when subjected to extreme loads, such

as those which exist in CO2 systems. This oil can be used both in

transcritical and subcritical systems.


Notes

Operating limits


application diagrams. Compressor application limits should not be

chosen for design purposes or continuous operation.

Performance data

Performance data for CO2 are based on 10 K suction-gas super-

heating at 50 Hz mains frequency. In case of subcritical operating

conditions, no liquid undercooling takes place. The performance

data for transcritical operating conditions are specified close to the

"optimal high pressure". The optimal high pressure is thereby rela-

ted to an ideal cyclic process.
